Automatic bottle blowing machine for plastic packaging product production

Abstract

The invention relates to an automatic bottle blowing machine for plastic packaging product production. The automatic bottle blowing machine for plastic packaging product production comprises a feeding assembly, two mold assemblies oppositely arranged on the two sides of the feeding assembly in a crossing mode, a transmission assembly and a bottle blowing assembly. The two mold assemblies are both slidably connected with the feeding assembly, mold grooves are formed in the opposite sides of the two mold assemblies, and the two mold grooves are in butt joint to form a mold cavity. The transmission assembly comprises a push plate and two swing arms, the two swing arms are in one-to-one correspondence with the two mold assemblies respectively, one ends of the swing arms are hinged to the push plate, the other ends of the swing arms are hinged to the corresponding mold assemblies, when the push plate moves towards the direction close to the feeding assembly, the two mold assemblies move back to back, and when the push plate moves towards the direction away from the feeding assembly, the two mold assemblies move relatively. The bottle blowing assembly is provided with an air outlet end communicated with the mold cavity. The problems that according to an existing mode that double telescopic pieces are linked to drive two molds to move synchronously, the strokes of the two telescopic pieces need to be accurately controlled, and operation is inconvenient are solved.

Description

technical field [0001] The invention relates to the technical field of bottle blowing machines, in particular to an automatic bottle blowing machine for producing plastic packaging products. Background technique [0002] Blow molding machine refers to a machine that blows bottles. The most simple explanation is a machine that can blow plastic particles (or preforms) into bottles through certain technological means. The bottle blowing machine is convenient and quick, and has a large molding capacity. After it appeared, it replaced most of the manual bottle blowing and was adopted by most beverage companies. [0003] The existing bottle blowing machine is provided with two moulds, which can move relative or opposite to each other. When the two moulds move to touch each other, a mold cavity is formed between them, and the injected and heated bottle is sent to the In the mold cavity, inject high-pressure air into the mouth of the bottle to blow the bottle into the desired shape...

AI Technical Summary

Problems solved by technology

[0005] In view of this, it is necessary to provide an automatic blow molding machine for the production of plastic packaging products, which is used to solve the problem that the existing double expansion parts are linked to drive the two molds to move synchronously. It is necessary to accurately control the stroke size of the two expansion parts. Inconvenient question
